Title: Improvements in or relating to method of distilling and fluidizing solids
IPC: C10B49/08
Filed: 1949-04-27
Abstract: 659,213. Distilling carbonaceous materials. PITTSBURGH CONSOLIDATION COAL CO. April 27, 1949, No. 11183. Convention date, May 15, 1948. '[Class 55(i)] Finely divided coal, oil shale &c. is circulated downwardly through a distillation zone in intimate contact with gas descending at a lower velocity and maintaining the coal in a dense fluid state ; solids and vaporous products are withdrawn at the bottom of the zone. For the low temperature distillation of high volatile bituminous coal, finely. divided coal from a hopper 14 is charged into a vertical retort 12 together with a high velocity stream of hot recycled residue delivered by a feeder 22 from a separator 44 the resulting temperature of the mixture ranging from 800‹ to 1400‹F. The relative amounts of coal and residue are adjusted so as to reduce the density of the solids in the retort to less than 75 per cent of that of the packed solids unmixed with gas and a valve 26 at the foot of the retort discharging into a separator 28 is regulated to produce a flow such that evolved gases are carried down with the solids but at a lower speed so that their upward superficial velocity in relation to the solids effects their fluidization. This velocity may range from 0.1 to 6 feet per second or move according to the size of the particles. Part of the residue is withdrawn through a conduit 32 and the remainder is passed with air through a combustion tube 40 in which a portion is burnt to provide heat for the distillation. Flue gas may be stripped from the recycled residue by inert gas introduced into separator 44. Gas may be introduced into the retort through a pipe 49 to supplement the fluidizing effect of the volatiles or build up pressure in the system which may reach 200-500 lbs. per square inch. In a modification the recycled residue is fiuidized with air, recycled gas, steam, or nitrogen, in a vessel above the retort and fresh coal is introduced at an intermediate point. Another apparatus provides two retorts in series with a narrower conduit connecting the bottom of one with the top of the other. Fresh coal may be introduced at a succession of inlets to minimize agglomerating tendencies, and air &c. may similarly be injected to maintain the temperature. To promote mixing of the solid streams they may be caused to swirl by return bends &c. in the conduits, or a mechanical agitator may be located at a right-angle bend.

Vapour and vacuum or low-pressure apparatus, arrangements of; frequency, changing.-An alternating magnetic flux or alternating current of a given frequency is produced from a source of alternating current of a different frequency by means of electron-discharge devices which rectify the supplied current and produce therefrom intermittent pulsatory currents of the given frequency and of a given displacement, from which the alternating magnetic flux or current is obtained. In the arrangement shown, three-phase current from the lines L, L<1>, L<2> is supplied to the electronic device 1 through a transformer T comprising delta-connected primary windings 2, 3, 4 and two sets of star-connected six-phase secondary windings 5 - - 10. The device 1 is provided with a single cathode 15 and two sets of six anodes 16 - - 21, each anode being connected to one of the secondary windings 5 - - 10. The cathode is connected to the star points of the secondary windings through windings 12, 13, the connections being such that the rectified currents produced in the device 1 traverse these windings in opposite directions. Between each set of anodes and the cathode are placed grids 22, 23. A generator G producing current of the given frequency is provided with two sets of slip-rings 25, 26, arranged to, produce potentials displaced by 180‹, the rings of each set being connected to the grids and cathode as shown. The rings are preferably insulated through half their circumference and batteries 27 may be included between the rings and the grids. The generator is excited through an adjustable resistance r from a batter 24, which also serves to heat the cathode. Intermittent pulsatory currents are thus produced alternately in the windings 12, 13, and these currents may be employed to produce an alternating flux in the stator windings of a motor, or an alternating current in a secondary winding 14. Specification 165,935 is referred to.
